Method of fishing refers to the techniques and tools used by anglers to catch fish. There are various methods of fishing, each suited for different types of fish and environments. Here are some of the most common methods of fishing:

Fish Harvesting

Fish harvesting refers to the process of catching fish from natural bodies of water such as oceans, lakes, and rivers, as well as from fish farms. Here are some important points to keep in mind when it comes to fish harvesting:

Fishing gear: Fishing gear includes a wide variety of tools used to catch fish, such as nets, traps, hooks, and lines. The type of gear used will depend on the target species, the location, and the fishing method employed.
Fishing methods: There are various fishing methods that can be used to harvest fish, including seine netting, trawling, longlining, and gillnetting. Each method has its advantages and disadvantages, and some methods are more sustainable than others.
Sustainability: Sustainable fish harvesting is crucial to ensure that fish populations are not depleted. This involves using fishing methods that minimize bycatch and avoid overfishing. It also involves complying with fishing regulations and quotas to prevent overfishing.
Processing: Once fish are caught, they need to be processed quickly to maintain their freshness and quality. This may involve cleaning, gutting, and icing the fish before transporting them to market.
Marketing: The marketing of fish is an important aspect of fish harvesting. Fish can be sold fresh, frozen, canned, or smoked, and different markets may have different requirements in terms of size, quality, and packaging.

Methods of Fish Harvesting

Fishing methods involve the use of different techniques or equipment used in harvesting fish.

Fishing is the activity of catching fish for human consumption or commercial purposes. There are various methods of fishing that have been practised for centuries. Here are some of the most common methods:

Netting

This involves using nets of different sizes and types to catch fish. Nets are made from fine cotton or nylon thread and are woven to various sizes and thicknesses. When the net is lowered into the water, weights made of lead attached to the edges of the net help it sinks to the bottom. When the net is pulled up, it encloses many fish, which are then caught between the holes called the mesh of the net.

Advantages of Netting

Efficient in catching large quantities of fish in a single operation.
Suitable for both shallow and deep waters.
Can be used to catch a wide variety of fish species.
Generally cost-effective compared to other fishing methods.
Relatively simple and easy to use.

Disadvantages of Netting

This can result in the capture of unwanted or non-targeted species (bycatch).
May cause damage to the environment by disrupting ecosystems and habitats.
Can be harmful to some endangered or protected species.
Requires a large number of nets to be effective, which can be expensive to maintain and replace.
May result in overfishing if not properly regulated.

Trapping

This method involves setting traps along water courses to catch fish. Traps are made from ropes or raffia and woven into various sizes to capture fish. There are many types of fish traps that can be made from bamboo, canes, raffia, oil palm or coconut palm fronds, wire, and wire mesh.

Advantages of Trapping

Can be selective in targeting specific fish species.
Minimal bycatch compared to other methods like netting.
Suitable for small-scale fishing operations.
Can be used in both fresh and saltwater environments.
Can be set up and left unattended for extended periods of time.

Disadvantages of Trapping

Can be time-consuming to set up and maintain.
Traps can be lost or damaged by natural events such as storms.
May not be as effective in catching large quantities of fish as other methods.
Can be expensive to build and repair.
May result in the capture of protected or endangered species.

Hooks and Lines

This involves using hooks tied to strings and baited with food to attract fish. The hooks are set along water courses to catch fish.

Advantages of Hooks and Lines

Can be used in a variety of water environments, from small streams to large oceans.
Can be selective in targeting specific fish species.
Minimal bycatch compared to other methods like netting.
Allows for catch-and-release fishing to minimize environmental impact.
Relatively inexpensive to use.

Disadvantages of Hooks and Lines

Can be time-consuming to set up and maintain.
Requires skill and experience to be effective.
Limited to catching one fish at a time.
Bait can be expensive and may attract unwanted species.
Can be dangerous to wildlife if hooks are not properly disposed of.

Use of Ultrasonic

This is an instrument that makes sound in the water to attract fish. Other methods of harvesting, such as netting, can be used to catch the fish.

Advantages of Ultrasonic

Can be used to attract fish from a distance, making it an efficient method.
Can be used in a variety of water environments.
Can be used in combination with other fishing methods to increase efficiency.
Does not harm the fish or the environment.
Can be used to target specific fish species.

Disadvantages of Ultrasonic

Can be expensive to purchase and maintain.
May not be effective in all water environments or with all fish species.
Can be disrupted by other sounds in the environment.
May require specialized training to use effectively.
Can still result in the capture of unwanted or non-targeted species.

Electrofishing

This method involves using an electric field connected to the water to electrocute fish. It can only be used for the total harvesting of fish.

Advantages of Electro Fishing

Can be used to catch large quantities of fish in a single operation.
Can be used to target specific fish species.
Does not harm the environment or other wildlife.
Can be used in both fresh and saltwater environments.
Can be used to collect data on fish populations.

Disadvantages of Electro Fishing

Can be expensive to purchase and maintain.
Can result in the death of captured fish if not properly handled.
Can be dangerous to humans if not used properly.
This can result in the capture of unwanted or non-targeted species.
Can only be used for the total harvesting of fish, not for catch-and-release fishing

Impaling

This involves using spears or harpoons or any sharp objects (wounding equipment) to attack and catch big fish, such as sharks.

Advantages of Impaling

Effective for catching large fish that are difficult to catch with other methods.
Does not harm the environment or other aquatic organisms.
Does not require specialized equipment or training.
Can be a culturally significant method of fishing in certain areas.

Screen or Barriers

Screens made with bamboo, raffia, or oil palm fronds are used to enclose portions of shallow water. When fish enter the trap/enclosed areas at high tide, they cannot escape at low tide when the water is reduced, so they are collected.

Advantages of Screen or Barriers

Effective for catching small to medium-sized fish in shallow waters.
Does not harm the environment or other aquatic organisms.
Does not require specialized equipment or training.
Can be a sustainable method of fishing if done responsibly.
Allows for easy selection of fish based on size and species.

Fishing without Equipment

Some aquatic animals can be caught without any kind of fishing equipment. They are picked up by hand from the mud and plants to which they are attached by the water current. Examples are periwinkles, oysters, and clams.

Advantages of Fishing without Equipment

Does not require any specialized equipment or training.
Can be a sustainable method of fishing if done responsibly.
Can be a culturally significant method of fishing in certain areas.
Does not harm the environment or other aquatic organisms.
Allows for easy selection of fish based on size and species.

Disadvantages of Fishing without Equipment

Can be time-consuming and physically demanding.
May not be legal in all areas or under all circumstances.
Can be easily disturbed by other aquatic organisms or human activities.
Limited to certain types of aquatic animals and habitats.

Preservation of Fish

Fish preservation is the process of keeping harvested fish fresh and safe to eat for an extended period. It is crucial to preserve fish to prevent spoilage, injury, or destruction, which could lead to a considerable loss for the farmer.

Preservation can be carried out in several ways to elongate the shelf life of the fish. Some of the most common methods include:

Refrigeration: This involves storing the fish at low temperatures to slow down bacterial growth, thus keeping the fish fresh for a more extended period.
Freezing: Fish can be frozen immediately after harvesting to maintain their freshness. Freezing halts the growth of bacteria, which can lead to spoilage.
Drying: This process involves removing the moisture content from the fish, making it unsuitable for bacterial growth. Dried fish can be stored for an extended period and used in soups or stews.
Smoking: Smoking is a method of drying fish that adds flavor and aroma. The smoke acts as a preservative by inhibiting bacterial growth.
Canning: Canning involves sealing fish in airtight containers, usually with added preservatives. Canned fish can be stored for several years without spoiling, and it is convenient for transport and storage.
Salting: This method involves rubbing salt on the fish or soaking it in a saltwater solution. Salt inhibits bacterial growth and can preserve fish for several months.
Pickling: Fish can be pickled in vinegar or brine, which lowers the pH level and makes it difficult for bacteria to thrive. Pickled fish can be stored for several months and is a popular delicacy in many cultures.
Fermentation: Fermenting fish involves allowing it to sit in a brine solution until the natural bacteria in the fish break down the flesh, creating a sour taste. Fermented fish can be stored for several months and is a traditional food in many parts of the world.
Irradiation: This process involves exposing the fish to ionizing radiation, which kills bacteria and extends the shelf life of the fish. However, irradiation is a controversial method, and some people are concerned about the potential health risks.
Modified atmosphere packaging (MAP): This method involves packaging the fish in a specific gas mixture that slows down bacterial growth and keeps the fish fresh. MAP is commonly used in supermarkets to preserve fish for longer periods.

Some of The Aims of Fish Preservation

Fish preservation refers to the various methods used to prevent the spoilage and decay of fish and seafood. The aim of fish preservation is to ensure that the fish remains safe for consumption while retaining its nutritional value, texture, and flavour. Here are some of the aims of fish preservation:

Extend shelf life: The primary aim of fish preservation is to extend the shelf life of the fish. This is achieved by slowing down or preventing the growth of microorganisms that cause spoilage, such as bacteria, yeast, and mould.
Maintain quality: Fish preservation methods are designed to maintain the quality of the fish by minimizing the loss of texture, flavour, and nutrients. This is important because spoiled or low-quality fish can pose health risks to consumers and lead to financial losses for the fishing industry.
Increase availability: Fish preservation methods can help to increase the availability of fish by allowing them to be stored and transported over long distances. This is important because many types of fish are seasonal and may only be available for a short period of time in certain regions.
Reduce waste: Fish preservation can help to reduce waste by allowing fish that would otherwise spoil to be saved for future use. This is important because the fishing industry can generate a significant amount of waste, which can have negative environmental impacts.
Improve safety: Fish preservation methods are designed to improve the safety of the fish by reducing the risk of contamination with harmful bacteria, parasites, or other pathogens. This is important because contaminated fish can cause foodborne illnesses that can be serious or even fatal.

Fish Processing

Fish processing refers to the activities involved in converting freshly caught fish into a product that is suitable for human consumption. The goal of fish processing is to preserve the quality and freshness of the fish while also making it more convenient for consumers to use.

The process of fish processing typically involves several steps, including cleaning, gutting, scaling, filleting, and packaging. These steps can vary depending on the type of fish being processed and the desired end product.

Fish processing is the transformation of raw fish into various food products that are suitable for consumption. It involves several techniques and methods that are designed to preserve the fish and improve its flavour, texture, and nutritional value. Here are some of the most common fish processing methods:

Cleaning and gutting: This is the first step in fish processing. The fish is cleaned, scaled, and gutted to remove any unwanted parts, such as the head, tail, fins, and internal organs.
Filleting: This process involves removing the flesh from the bones of the fish. Fillets are a popular way to consume fish as they are boneless and easy to prepare.
Curing: Curing is a process in which the fish is salted or smoked to preserve it and give it a unique flavour. Cured fish can be stored for long periods of time without refrigeration.
Drying: Drying is another method used to preserve fish. It involves removing moisture from the fish by exposing it to the sun, wind, or a dehydrator.
Freezing: Freezing is one of the most popular methods of preserving fish. It involves freezing the fish at a temperature of -18°C or below to prevent spoilage.
Canning: Canning is a process in which the fish is cooked and then sealed in an airtight container. This method allows the fish to be stored for long periods of time without refrigeration.
Pasteurization: Pasteurization involves heating the fish to a specific temperature for a specific amount of time to kill bacteria and other pathogens. This process helps to extend the shelf life of the fish.
Fermentation: Fermentation is a process in which the fish is allowed to undergo a natural fermentation process, which improves its flavour and nutritional value.
